Studdy Solution
Verify the solution by substituting $x = 30$ back into the expressions for the angles and checking their sum:
- First angle: $(30 - 2)^\circ = 28^\circ$ - Second angle: $(3 \times 30 - 9)^\circ = 81^\circ$ - Third angle: $(2 \times 30 + 11)^\circ = 71^\circ$
Check the sum:
$28 + 81 + 71 = 180$
The sum is $180^\circ$, which confirms our solution is correct.
The value of $x$ is:
$$\boxed{30}$$
